Best Straight Edge Quality and Price to buy?

[Greg Parrish]

I think these are pretty reasonable.

that’s what I have. The 50” version. It’s .003 accurate overall and .001 per foot accuracy according to Fulton. For table saw, jointer, etc leveling it works great. It also confirms my 48” empire level, which claims identical accuracy, is flat and accurate.

I think these are great value without stepping up to a much pricier starrett machinist steel straight edge.
